Ken,

It may be that you are over-analyzing it.

Simply increase the audio to produce 4 bars with the 5th bar
flickering.  On the K3, that is the "NO ALC" point - the "less than 5
bars" area of the "ALC" meter is more or less like a VU meter, and is
done that way to allow you to properly adjust the audio level.
You must have adequate audio drive to allow the K3 power control to
operate correctly.  Control the power output with the power knob, not
the audio.

The K3 is different in this respect from most (or all) the other
transceivers on the market.  The sage advice of NO ALC offered for those
other transceivers does not work for the K3 (and K2 and KX3).

Yes, the K3 is 'riding herd' on the power output, and that is in PEP.

73,
